i will prepare an updated patch that works if the target has no musl

Updated the patch, this time I tested it separately.
(The test revealed that -mmusl was not wired up properly
in linux.opt through the "Negative" directive, now fixed).
A default dynamic linker name is defined for musl: "/dev/null".
(The arch specific headers have to be updated to undef the
MUSL_DYNAMIC_LINKER* macros).
(Other options were considered such as print an error with %e,
but then the user cannot override it with -Wl,-dynamic-linker)
The other parts of the patch (config, include path reordering)
are not changed.
